Application filedDecember 24, 1912. Serial No. 738,420.

To all whom it may concern Be it known that we, LUCENA M. MORDEN, acitizen of the United States, and JOHN BUCHANAN, asubject of the King ofGreat.

Britain, both residing at Waterbury, in the county of New Haven andState of Connecticut, have invented certain new and useful Improvementsin Book-Rings, of which the following is a specification.

This invention relates to book rings adapted particularly for usewith'looseleaf books, the object of the invention being to provide animprovedring, which may be properly designated as a knuckle ortoggle-joint ring, in which the ring, usually comprising two halfsections hinged together, is provided with a spring. so carried by thering that when the ring is being opened it will, when it reaches acertain point in the opening thereof, flv open, and likewise on beingclosed itwill, when it reaches a certainpoint in the closing thereof,fly closed, and will remain in either of these positions.

Theobject of the present improvement, thereforepis the provision ofanimproved ring of the character described constructed of two hingedmembers carrying a spring substantially equally and simultaneouslyeffective on both members of the ring so that the ring has what may betermed a toggle joint connection.

The present improvement has to do with rings which are usually usedindependently of a back, and therefore they must havein themselves themeans for opening and closing them, and formaintaining. them in eitherof these positions, and not depend upon the back or a part connectedtherewith for accomplishing these results.

In the drawings accompanying and forming part of this specification,Figure 1 is a view of one form of ring closed; Fig. 2 isa view of thesame ring open; Fig. 3 is a view of the ring without the spring; Fig. 4is a view of the spring which may be usedwith this form of ring; Fig. 5is an under side view of the ring. shown in Fig. 1; Figs.6 and 7illustrate views of a ring of a somewhat difierent construction, closedand open respectively: Figs. 8,9 and 10 illustrate a ring of a stilldifferent form of construction, the last figure illustrating theopposite side ofthe ring from that shown in Fig. 8, the

'ringbeing open; and Fig. 11 is a view oft.

somewhat difi'erent form of ring :construction.

Similarcharacters of reference indicate corresponding parts throughoutthe figures of the drawings. t

In all of the constructions illustrated herein it will beobservedthatthe ring 2 comprises two semi-circularmembers 3 and 4 having some usualform of meeting ends 5, these members being hinge-connected at theiropposite ends. In some forms the hinge connection comprises the usualpivotal connection or pintle between the members, as in Figs. 1 to 5,while in other forms the pintle or pivot is carried by pockets ornotches in the meeting edges of therings,*as in Figs. 6, 7 and 11, whilein,Figs. 8 and 9 the pivotal connection is obtained by means of aprojection or tongue carried by one member and extending into a recessor groove of the other, forminga hinge on the order of a butt joint, andin all of them a spring is provided so located with relation to thehingeconnection that. the ring has to all intents and purposes atoggle-joint connection, such spring having substantially equalefficiency on both members of the ring and in.

the present instance extending about the same distanceat each side ofthe pivotal connection.

In the form shown in Figs. 1 to 5 the hinged ends of the ring membersarepivotally connected by a pivot 6 extending through rabbeted oroverlapping portions 7 of the ring members, which are for this pur' posepreferably cut away a predetermined distance at each sideof the pivot,as M8, and the outer margin of each ring member is provided with a notch9 for the reception of the spring 10,which spring in the presentinstance is of an elongated loop formation and suitably bent tohave itsouter ends 11 extend into the notches 9 in the margins of the ringmembers and also bent intermediate such ends. as at 12, to conform tothe peripherv of the ring. a

In the form shown in Figspfi and 7, the meeting ends ofthe ring membersare provided with notches 13 for the reception of a pin 14 and are alsoprovided with slots 15 through which a spring, 16 extends, this springbeing provided with a loop 17 ex tending intothe interior of the ring,and a pair of laterally extendingends 18 having while the spring fits inthis cut away or recessed portion and thelaterally extending ends 21 ofthis spring extend into openings and may be headed over on the oppositeside of the ring in any suitable manner,

In all forms of the improvement it will be observed that the spring isprovided with ends of onefo rn or another which engage directly with thering members themselves and is also provided with what may be considereda loop intermediate portion extendmg around or past the hinge connectionand conforming in some forms thereof to the peripheral shape of thering. The spring is located in such a manner that the ring will bemaintained closed or open, and both halves of the ring may be openedtogether equally, and when partially open the, spring will cause them tofly open and remain open and when partially closed beyond a certainpoint the spring will cause them to fly closed and remain closed.

In all forms of the device shown, it will be observed that the spring islocated centr'ally with relation to the pivotal point of the membersforming the ring and that the spring has part connected to each of saidmembers, this connection being obtained by inserting an equal portion ofthe spring into ea'ch'of the ring members'so that the spring et's withequal force on both members of the ring;

It is to be understood that the various details may be more or lessmodified without departing from the spirit or scope of this improvement.7

We claim as our inventionf I 1. A book ring comprising two half sectionshinged together and a spring projecting int'o said sections and actingequally on both for maintaining the'ring open or closed and shooting theopening or closing thereof after it is partially opened 'or closed.
